Now Christmas is past, Twelfth Night is the last
To the Old Year adieu, Great joy to the new

January 5th is the twelfth night of the 12 days of Christmas. Those of the Celtic persuasion would drink the wassail tonight and pass a cake into which a token was placed. The person to find the token was king or queen of the twelfth night. http://historiccamdencounty.com/ccnews93.shtml
